JOHN R. MITCHELL, OF NEW YORK, N. Y.

PORCELAIN THREAD-GUIDE.

Specification of Letters Patent.

Patented Apr. 24, 1917.

Application filed November 27, 1915. Serial No. 63,836.

To all whom it may concern:

Be it known that 1, JOHN R. MITCHELL, a citizen of the United States, residing at New York, county and State of New York, have invented certain new and useful Improvements in Porcelain Thread-Guides, of which the following is a specification.

This invention relates to improvements in hooks for drop-wires on doubling or other textile machines.

The object of the invention is to provide certain improvements over the construction shown in my prior Patent No. 774,593, and whereby the thread will be more effectively prevented from escaping from the hook.

The invention is illustrated in the accompanying drawing which is a side elevation with a part in section.

Referring to the drawing, it will be seen that the hook of the present invention and the patented hook are ol -generally similar appearance and that each comprises a body 10, which is preferably of glazed porcelain, havlng a socket 11 to recelve the wire or other part to which the hook is attached.

At the upper end of'the body is an elongated recess 12 having rounded ends and one side of which is substantially straight as indicated at 18. An upwardly inclined slot 14 opens into the recess 12 above the bottom thereof and it will be noted that the lip 15 at one side of the outer end of the slot 14 projects beyond the opposite lip 16 so that the thread in being drawn upwardly along the side of the hook will engage the lip 15 and be directed thereby through the slot 14 into the recess 12. A finger 17 projects into the recess 12 from the side containing the slot 14 and above the slot. The upper end 18 of the finger is extended well toward the upper end of the recess 12 and forms a pocket 19 in which the thread is normally carried. The lower side of the finger 17 is preferably a continuation of the upper side of the slot 14 so that when the thread is drawn upwardly along this slot it will be carried directly into the pocket 19. The recess 12 extends below the slot 14 a suflioient distance to form a pocket of substantial depth so that in case the thread escapes from the pocket 19 it will drop into the lower end of the recess and will have practically no tendency to escape through the slot 14.

Animportant feature of my present invention resides in having the retaining finger 18 directed rearwardly and upwardly from the front or receiving side of the guide so that a thread in escaping from the pocket 19 will be thrown against the back wall 13 and will have no tendency to fall into the slot 14, but will, instead, drop into the recess or pocket 12. Thus a thread which becomes slack through breakage or for other reasons will not escape from the guide.

Having thus described the invention, what is claimed and desired to be secured by Let ters Patent is:

1. A hook for guiding thread in textile machinery consisting of a body having an elongated eyeat its upper end, an upwardly inclined slot leading into said eye above the bottom thereof, and a finger projecting inwardly and upwardly into said eye from the side containing said slot and forming an extension to the upper wall of the slot, whereby a thread escaping from the finger will be thrown against the back wall of the eye.

2. A hook for guiding thread in textile machinery consisting of a body having an elongated eye at its upper end, the eye hav ing rounded ends and one substantially straight side, an upwardly inclined slot leading into said eye above the bottom thereof and opposite said substantially straight side, and a finger projecting inwardly and upwardly into said eye from the side containing said slot and above the slot to form a pocket to normally carry the thread.

In testimony whereof I afiix my signature.

JOHN R. MITCHELL.
